Why can not change the fuse when replacing the fuse
Change the crude after the fuse does not work, the current is too large, it will burn out the meter
Fuse is to limit the current to ensure that the meter does not burn
the resistance becomes smaller, in the case of a larger current May not burn, so that the role of the protection of electrical appliances
so that will not burn the electrical use of the fuse resistance and thickness is inversely proportional to if the thick fuse,
The role of the fuse is when the circuit current is too large and timely fuse,
